, of being a terror attack. large explosions. a big bomb in oslo, and then a guy who steals is police uniform or creates one and then goes to the camp, and he also had mom-making materials or a bomb on the island. you begin to say this is an awful big sort of incident to have just one person. so for a lot of reasons i think people assume, based on recent history over the last ten years, of an international terrorism conspiracy. we're now hearing maybe not. this may be a right wing extremist. somebody from their midst. >> fran, this reminds me of the oklahoma city bombing. when that happened it was also so big the initial idea was this had to be a group of some sort, and i guess it was. there were two people involved. it was not a massive group nor a big effort. >> that's right. i think one, you will find this will be hard to do alone. the times square bomber, it's hard to have one guy to get the materials and put it together correctly and detonate it. it's reasonable to suspect he had some amount of help. and we are hearing from media sources the individual in custody may have been a farmer.
